Definitely unrelated to bug #582679. What if the version of Eigen you
use?

squaredNorm should be defined in
/usr/include/eigen2/Eigen/src/Core/MatrixBase.h (the path can be
different depending on where you installed it).

This log result from a second scons. A first scons, executed just before, gave me (moreover to this error in Cell.cpp) errors linked with **Qt** files, as in https://launchpad.net/bugs/582679 it seems.
